REQUEST: Food for the Heart

I'm not used to asking others for help getting things that are necessary to me, but I wanted to give it a go on the off chance this might actually happen. I live in Los Angeles, CA. So I don't have the money to get my family Christmas presents this year, my idea was I would get groceries for them and cook for them while I stay with them. But I don't have money for that either, I was wondering if someone could take me grocery shopping and get the bill for me? Another thing would be, my backpack for school is ripped, and I'm running low on school supplies. So if anyone would be able to help with these things or one of them I would be forever grateful. I'm glad a page like this exists :)
